单个Morris-LeCar神经元模型通过调节钾通道的平衡电位，可以产生多种自发放电节律模式，如发放和爆发活动。在两个电耦合的完全相同的Morris-LeCar神经元中，结果表明，耦合强度的增加导致完全同步。该临界值是同步流形的条件Lyapunov指数、平均同步误差和最大同步误差的函数。基于定义良好的相函数，进一步研究了两个耦合Morris-LeCar神经元的相位同步问题。
A single Morris-Lecar neuron model can produce a variety of spontaneous firing rhythm patterns, such as spiking and bursting activities, by adjustment of the equilibrium potential of potassium channel. In the two electrically coupled identical Morris-Lecar neurons, it is shown that the increase of the coupling strength induces complete synchronization. The critical value is determined as a function of the conditional Lyapunov exponents of the synchronization manifold, the mean synchronization error and the maximum synchronization error. Based on a well-defined phase function, phase synchronization of two coupled Morris-Lecar neurons is further studied.
